Absolutely love the new campaign from the Optimum Population Trust: do your bit for addressing climate change by having fewer children - or even no children. The lifetime CO2 emissions of a UK citizen amount to 750 tonnes (the equivalent - apparently - of 620 return flights between London and New York), so the extra 10 million by which our population will rise between now and 2074 will, over their lifetimes, emit around 7½ billion tonnes of CO2..."births averted" is probably the most single most substantial and cost-effective intervention that governments could be using

The World Health Organization recently published some data showing that each overweight person causes and additional one tonne of CO2 to be emitted every year. With one billion people overweight around the world-of whom at least 300 million are obese-that's an additional one billion tonnes.

...the core values that underpin sustainable development - interdependence, empathy, equity, personal responsibility and intergenerational justice - are the only foundation upon which any viable vision of a better world can possibly be constructed

Peace, non-violence, human rights and the environment - if only everybody saw these as the seamless whole that they are

What may be possible for a minority of humankind, albeit at great cost, simply cannot work for the humankind. Our kind of progress depends on lacerating the Earth,on gouging out its riches, on stripping is life-sustaining skin of soil and forest

The huge arrogance of the companies developing GMO crops and their determination to destroy the line of accountability which links the developer to the product is breath-taking. When something goes wrong, as it inevitably will, there will be a great benefit to those who have taken a stance against genetically modified organisms.

It's not enough simply to wear the badge of corporate responsibility. Business must accept that real change is the only response to climate change and other environmental crises
